### Data Analysis and Probability

bar graph A graph that uses vertical or horizontal bars to display data.
box-and-whisker plot A method of showing how data is distributed by using the median, quartiles, and minimum and maximum values.
circle graph A way to display data by using a circle divided into non-overlapping sectors.
combination A selection of a group of objects in which order is not important.
complement All outcomes in the sample space that are not in and event.
compound event An event made up of two or more simple events.
cumulative frequency The frequency of all data values that are less than or equal to a given value.
dependent events Events for which the occurrence or nonoccurrence of one event affects the probability of the other event.
equally likely Outcomes that have the same probability of occurring.
event An outcome or set of outcomes in a probability experiment.
experiment an operation, process, or activity in which outcomes can be used to estimate probability.
experimental probability The ratio of the number of times an event occurs to the number of trails, or times, that an activity is performed.
fair When all outcomes of an experiment are equally likely.
frequency The number of times the value appears in the data set.
frequency table A display that list the number of times that each data value occurs.
histogram A bar graph used to display data grouped in class intervals.
independent events Events for which the occurrence or nonoccurrence of one event does not affect the probability of the other event.
interquartile range (IQR) The difference of the third and first quartiles in a data set, representing the middle half of the data.
line graph A graph that uses line segments to show how data changes.
mean The sum of all the values in a data set divided by the number of data values.
median For an ordered data set with an odd number of values, the median is the middle value. For an ordered data set with an even number of values, the median is the average of the two middle values.
mode The value or values that occur most frequently in a data set.
odds A comparison of favorable and unfavorable outcomes.
outcome A possible result of a probability experiment.
outlier A data value that is far removed from the rest of the data.
permutation An arrangement of a group of objects in which order is important.
prediction An estimate or guess about something that has not yet happened.
probability A number from 0 to 1 that is the measure of how likely an event is to occur.
quartile The median of the upper or lower half of a data set.
random sample A sample selected from a population so that each member of the population has an equal chance of being selected.
range The difference of the greatest and least values in the data set.
sample space The set of all possible outcomes of a probability experiment.
stem-and-leaf plot A graph used to organize and display data by dividing each data value into two parts.
theoretical probability The ratio of the number of equally likely outcomes in an event to the total number of possible outcomes.
trial In probability, a single repetition or observation of an experiment.
